This invention relates to a pneumatic wheel and has for "its" object to provide a wheel of such class in the, manner as hereinafter-set forth possessing the samec'ushioning function as the type of pneumatic tired wheel now in general use and further reduc ing the possibility of punctures and blowouts toaminimumi 1 I Further objects of the'in'vention are to provide, in a manner as hereinafter set, forth a pneumatic wheel which is simple in its construction and arrangement, strong, durable, thoroughly efficient j in its use, readily assembled, and comparatively inexpensive to manufacture.

iVith the foregoing and other objects in view, the invention consists of the novel con Figure 3- is asection; on t characters struction, combination and arrangement of parts as licrelnaftenmore specifically de scribed; and illustrated 1n the accompanying drawings wherein'is shown an embodiment of the inventlon, but 1t is to be ure 1; I I a.

tuted. Preferably the construction 'offthe wheel is set up withthe annulus 1.

Surrounding and spaced fromthe-annulus at as well as being coupled therewith, "is a pneumatic cushioning element conslstlng-of an inner tube whichis enclosed by a shoe 8 of the split type and which isforined at its inner side with apair of flanges 9,110,

interengaging with each other at their inner faces whereby when the flanges 9 and 10 are in abutting relation 1n cross section, a

rectangular body will be provided. :The outer side of the shoe 8 isformed with a circumferentially extending rib 11,", of rectangularcross section and whichc'orresponds in contour, to' the flanges 9 and '10 when they ai'e infabutting relationw Atthe point of oinder oftheiflang'e 9,;fas well as the flange 10', with the body portionfS of the shoe, each of said flanges is in-cut as at 12 to provide an annular groove.

Each side of the rib 1-1 at the point of joinder thereof with the body portion: of the; shoe is in-out as at 13' to provide anannular' groove. The

and connected to the latterand extending 7 5 shoe 8 completely enclosesthe inner tube 7 through the flange 9 i s atvalvedair filling tube 14 ofany suitable forim but of a length I to project a substantial "distance from said flange: 9, see Figure 3".

1 Thepneumaticcushioning element'is'coupled with the annulus 1 by apair jof oppo sitely disposed'annular clamping members referred to generally by the referencechar- 'acters16 and 17. "The clamping members 16 and 17 are constructed alike; with this exception that the clamping member 17 is' formed witha slot 18 for the passage fofthe I airvalve element 1 1;"see Figure 3. I

f In vertical section; eachof the clamping members consistsof a vertical portion 20, which is termed the intermediate part thereof, and an innerand an outerangle shaped portion 21; '22, respectively The portion 21 is of "greater length than the portion 22,

The flanges of'the' outer port-ion 21 are dic'ated a t "2 3,' 24' and those of the inner 7 portion 22, at 25, 26. The flange 24 is inturned to provide a clamping nose 27. \Vhen the clamping members 16 and 17. are mounted 1n position, the outer portions 21 thereof abut against the flanges 9, 10 and thenoses 27 of the flanges 24 engage in the grooves 12 and the inner portions 22 abut against the annulus 4 and extend against both sides thereof. The intermediate parts of the clamping members 16 and Hare secured together by hold fast devices 22 and the flanges 26 of the inner portions 22 are secured to the annulus 4 by the hold fast devices 29. The hold fast devices 28 and 29 detachably secure the clamping members 16 and 17 inposition with respect to the annulus 4 and pneumatic cushioning element.

The tire 15 1s connected or coupled with the pneumatic cushioning element by a pair of oppositely'extending annular clamping angles with respect to each other. The

flanges 38 of each inner portion 34 .are inturned as at 39 to provide a clamping nose. The noses engage inthe grooves 13 of the rib 11. The intermediate portions 32 of the clamping members 30, 31 are detachably connected together by hold fast devices 40. hen the clamping members are arranged in coupling position with respect to the tire 1 5. and pneumatic cushioning, element, the

' outer portions'33 abut against the tire 15 and also bear against the sides thereof.

"The inner portions 34 abut against the rib 11 and bear against the sides thereof and further extend into the grooves 13. The engaging, of the noses 27 and 39 in the grooves 12 and 13 respectively connect the two pair of clamping members with the pneumatic cushioning element. 7

Each of the outer clamping members is formed throughout with spaced reinforcingribs. Certain of the ribs extend from an inner portion of a clamping member and the other of the ribs extend from the outer portion of the clamping member. The ribs extending from the inneryportion of the diate part of the clamping member.

clamping member are alternately disposed with respect to the ribs WlllCllextend trom the outer portion of the clamp ng men'ibcr.

The ribs are of slightly less length than the length in vertical section of the interme- Y "he ribs which extend "from the inner portion ot a clamping member are indicated at and those that extend from an outer portion of the clamping member are indicated at 42. The ribs are formed on the outer side of the clamping member. The ribs are rounded in sectional plan, as indicated at 43 in Figure 5. In Figure 4 one of the ribs is illustrated and is shown as extended from the inner portion of a clamping member. The ribs are disposed 'in' pairs between each pair 0t hold fastdevices 40 and the ribs of each pair are spaced from each other. One of theribs of the pair extends from inner portion of the clamping member and the other of the pair extends from-the outer portion of the clamping member.

The inner clamping members are provided with ribs 44 on the intermediate portions'th-ereo'f. The ribs 44 are not arranged in pairs as the ribs tormed on the outer clamping members The ribs 44 extend from the outer portions towards the inner portions of the 'inner clamping members.

The ribs 44 are of the same form as the The two pair of clamping members will hold the tire member 15 and pneumatic cushioning element firmly'and will prevent any water or moisture from coming incontact with the inner tube 7.. Undensuch conditions. the life of the inner tube '7 of the pneumatic cushioning element is materially obstructions or any obstacle which mayin jure the same. i I r 7.

It is thought the many advantages ofa pneumatic wheel, in accordance with this invention, can be readily understood. and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood: that changes inthe details of construction can be had which will fall within thei scopeot' the invention as. claimed. r
